Specification of Letters Patent. Patented July 17, 19117.

.Application filed October 24, 1916. Serial No. 127,375.

To all whom t may concern:

Be it known that I, WILLIAM Gr. HU'roI-II- soN, a citizen of the United States, and a resident of Valparaiso, in the county of `Porter and State of Indiana,have`made certain new and useful Improvements in Ventilators, of which the following is a specification.

My invention is an improvement in venti-y lators, and has for its object to provide a device of the character specilied especially adapted for use with railroad cars, wherein a casing is provided which may be arranged in the ventilator openings at the tops of the cars, the casing being open at the inner side and at its ends, and having a seri-es of longitudinally extending baiiie plates arranged in approximately parallel and overlapping relation at one end of the ventilator casing to form a series of passages extending longitudinally of the casing, and wherein a door is hinged to the opposite end to open loutf ward, and a partition is arranged at the inner side of the door between the same and the baiiie plates.

In the drawings: v

Figure 1 is a horizontal section through a ventilator in place.

Fig. 2 is an enlarged detail of Fig. 1.

Fig. 3 is a perspective view showing the door.

Fig. 4 is a section on the line 4-4 of Fig. 1.

Fig. 5 is a top plan View of one of the regulating valves.

The present embodiment of the invention is shown in connection with a car body 1, the ventilator being arranged in the opening 2, and the casing of the ventilator is of a size to fit closely within the opening. This casing is substantially U-shaped in cross section, comprising an arched body 3 and side walls 4, and the casing is open at its inner side and at one end, as shown.

The other end of the casing is partially closed by a transverse partition 5, said partition being at the open side of the casing, and leaving an outlet or passage 6 between the body of the casing and the partition.

A door 7 is hinged at this point as indicated at 8, to open outward, and a longitudinally extending partition 9 is arranged at the inner side of the door, the partition extendino` somewhat less than half the length of the causing. t

A series of pairs of battle plates 10y andy 10a is arranged in the casing at the opposite end from the door, the members of the pairs `being approximately parallel and spaced apart from each other to form passages be-V tween the same.

The pairs overlap, as shown in Figs. 1 and 2, the pair at the end of the casing being nearer the body and overlapping the succeeding pair in spaced relation, thus` forming another passage between the adj acent members of the adjacent pairs.

In the present instance three (3) pairs of plates are provided, and each pair overlaps the adjacent ends of thesucceeding pair, the

last pair overlapping the adjacent end of the partition 9. j

As shown in Fig. 4, each plate 10s-10a` is provided with laterally extending flanges 11 at its side edges, and the flanges 11 of each plate 10 fit against theinner faces of the side walls 4 of the casing, while the flanges 11 of the plates 10a fit against the inner faces of the flanges 11 of the adjacent plate 10.

An angle. plate 12 is secured to the inner face of each sidewall of the casing, and these angle plates secure the iianges 11 of the plates 10 and 10L to the casing. The angle plates are secured to the side walls by means of Vrivets 13 or the like, with one portion extending laterally inward above the baille plates, to prevent the entrance of rain and the like.

As shown in Figs. 1 Vand 2, a stop plate 14 extends longitudinally from the inner end of the partition 9 and the door 7 is hinged to this stop plate. When the ventilator is in place the stop plate laps against the outer face of the car, and the outermost plate 10 at the opposite end of the casing is extended beyond the said end, as indicated at 15, to perform a like service at the said end.

A strip 16 of perforate material, as for instance wire, cloth, is arranged over the ends of the passages between the baille plates, the said strip preventing the entrance of cinders and the like.

In use, the ventilator is arranged as shown in Fig. 1, with the door 7 at the rear end of the casing. When the car is traveling, the air will enter at the end of the casing remote from the door, and will pass out at the door opening 6, acting in the manner of an injector to draw the foul air from the car the thrilghy passages between 'the plates '10 aad. l'Qof 'the paesana the plates 'loa 10 f the adjacent pairs. Each of the 4 Saldinaiis is a valve or damper 17, which is throughv the passages between the baffle plates.

The door 7 will regulate the force of the 4provided with pintles or jeunalpins 18 journaled in the sides of the casing 3 4.

'eoil Lsprirngi 19 enircles oneyof these vpin in fopenlpsfition,. A 'buffer' 20A is arranged 2.6 e

I claim l. In a ventilator, a series of pairs of longitudinally extending approximately par allel batle plates, said plates being spaced apart and the pairs being arranged with the outermost pairs overlapping the innermost pairs, and with the outermost pair at the inlet end of the casing, valves for closing the passages between the plates, springs normally holding the valves open, and a buffer for supporting each valve in an lnclined position to permit th'e airt'o have access thereto to Vclose' the saine. p
